That's okay, there's no need to be sad as she's a happy well trained female dog and I chose the collar for a specific purpose after research. She has a delicate neck and spine and the collar is for her safety now that she's a senior in the event pressure is put on the lead. She could wear a collar with needles in it and it wouldn't matter as she's already trained and doesn't pull.

You should feel worse for the puppy, she never stops pulling on the harness and has damaged her throat doing it!
